Microsoft Sentinel is a cloud-native Security Information Event Management (SIEM) service that offers intelligent security analytics to help identify threats and manage risks. As part of the SC-200 Microsoft Security Operations Analyst exam, understanding how to utilize Microsoft Sentinel’s data connectors is key. These components collect data from different sources and make it accessible for instance correlation, threat detection, and response.
To create and use these data connectors efficiently, there are certain prerequisites and considerations. Knowing these requirements is an important aspect of the exam and the daily responsibilities of a Security Operations Analyst.
Prerequisites for a Microsoft Sentinel Data Connector
Microsoft Sentinel supports a wide range of data connectors enabling smooth integration with multiple sources. Before setting up a data connector in Microsoft Sentinel, there are some prerequisites and permissions that you need to understand:
- Permissions: To connect data sources to Microsoft Sentinel, you will need specific permissions. If you are using Azure active directory users, they should have one of these roles: Global Administrator, Security Administrator, or Security Operator. However, the complexity of your environment may demand more custom roles.
- Azure Subscription: An active Azure subscription is mandatory to utilize Microsoft Sentinel and its capabilities including data connectors.
- Workspace: You need an active workspace in Azure Log Analytics. Log analytics will store and manage the data.
- Data Source-specific Considerations: Depending on the data source, there might be additional prerequisites. For instance, Microsoft 365 Defender requires Microsoft Defender for Endpoints, and Microsoft Defender for Office 365.
Key Steps in Setting up a Microsoft Sentinel Data Connector
Here are the general steps to set up a Microsoft Sentinel data connector, using the Azure Sentinel connector as an example:
- Sign in to the Azure portal: Use your Azure account credentials that have the required permissions.
- Navigate to Azure Sentinel: Select your preferred workspace.
- Add Your Connector: Go to
Data connectorsfrom the configuration pane and choose theAzure Active Directoryconnector. ClickOpen connector page. - Configure the connector: This step varies depending on the nature of your data source. For the Azure Active Directory connector as an example, you will need to first
Install Azure AD logs, and thenConfigure the Azure Active Directory Tenant. - Apply settings: Once the configuration is done, click
Apply. - Validate the Connection: Once done, you can check out for received logs to validate the connection.
Remember, these are high-level guidelines. Depending on the specific connector, the exact steps and settings will vary.
In conclusion, understanding data connectors’ prerequisites and configurations is crucial in the SC-200 Microsoft Security Operations Analyst exam. Grasping these details also goes a long way in ensuring one is well equipped to deal with real-world scenarios in Microsoft Sentinel’s application.
